IMPROVEMENT IN KNlFE-SCOURERS.

Specification forming part of Letters Patent N o.

December To all whom it may concern:

Be it known that I, CLARENCE V. HADLEY, of East Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Knife- Scourers, of which the following is a specification In the plate of drawings, Figure 1 represents a perspective view of my invention Fig. 2, a horizontal section of the same; Fig. 3, a perspective view of the frame; Fig. 4 a perspective view of the adjustable casin g and Fig. 5 a detached view of the two revolving sleeves.

In the drawings, A represents a bed-piece, suitably adapted to be fastened to a table or other support. BB are two revolving sleeves, made of india-rubber, mounted on shafts a a, having projecting, square ends. These rub ber sleeves B are placed vertically and side by side upon the bed-pieceA, with theirsquare projecting ends in a groove, c, of the bedpiece A, and in a slot or groove, d, of a hori zontal plate, C, which issecured to the bed piece A through a semi-cylindrical casing, D, Within which stands one of the rubber rollers B, E, a semi-cylindrical casing, similar to casing D. This casing E has square ends f fitting in the grooves c and d before referred to, and within it stands a rubber sleeve, B. The casing E is free to be moved back and forth together with the square ends of the rubber roller B, which is within it, are shaped relatively to each other, so that the square ends of the casing will have a bearing against the square ends of the sleeves without contact, A

and with a space, g,

between the rubber body of the sleeves and the inside of the casing.

192,865, dated July 10, 1877; application filed 12, 1876.

At the unsupported end h of the sleeve-receiving plate C the groove d is open to admit of the sleeves B and casing E being inserted and removed at pleasure F, a cam-surface on outside of easing E, and G a lever havingcam-edge. The lever swings vertically on a pivot, Z, of the bed-piece, has a handle, m, for operating it, and is arranged so that, by properly swinging it, its cam-edge can be brought to bear against the cam-edge of the casing, so as to firmly jam one sleeve B against the other sleeve B, and there hold it; E, strips of emery-cloth, wound one strip about each sleeve B, and the outer end of each stripis disposed outside of the casings D E, as shown in Fig. 2, i

With the emery-cloth on the sleeves, and the sleeves tightly jammed together, as described, to clean or scour a knife'blade, draw it back and forth between the sleeves.

As the emery-cloth becomes worn, first loosen up the sleeves, and then draw off the cloth from the sleeves sufficiently to give a fresh and unworn surface, when again set up the sleeves, as before. i

Having thus described my invention, what I claim, and desire to secure by Letters Patent, rs-

The combination of the grooved bed-piece A, fixed upright casing D, and grooved plate 0, with the adjustable upright casing E, em-

cry-sheathed rubber sleeves B B, and a camlever, G, all substantially as and for the purpose described.
